The Saint-Charles Sud slag heap, entirely wooded, has been converted into a place of discovery and relaxation. It adjoins the Bois du Cazier site, where the biggest mining disaster in the history of Belgium took place on the morning of August 8, 1956. The summit hosts a panoramic observatory on the region, at nearly 250 meters above sea level. A path has been laid out to facilitate the ascent of the slag heap.

The Pétria slag heap, known as “Seat No. 1” was created between 1870 and 1926. It was then exploited and reworked as part of the recovery of coal shale and residual coal. Bought by the City of Fontaine-l'Evêque in 1995, the Pétria slag heap was classified as a "Natura 2000" zone in 2002. In 2020, the site became an approved nature reserve for batrachians following substantial developments aimed at protecting natterjack toads and midwife toads: excavation of temporary ponds, cleaning of sludge tanks to make them a breeding site, cleaning and clearing of the Babelone pond. https://www.destinationterrils.eu/fr/terril-du-petria

The long slope is doable, she also goes straight to straight. The descent, however, is a different soup... Good luck!
